Pseudo-second order kinetics for the adsorption of (a1) RR120, (a2) RY167, and (a3) RB222 onto the CL powders, respectively (m = 0.3 g, V = 50 mL, C0 = 50, 100, 200, and 300 mg·L−1, T = 30 °C, pH = 3.0); intraparticle diffusion kinetics for the adsorption of (b1) RR120, (b2) RY167, and (b3) RB222 onto the CL powders, respectively (m = 0.3 g, V = 50 mL, C0 = 50, 100, 200, and 300 mg·L−1, T = 30 °C, pH = 3.0).
